Abstract: An object-based data storage service receives a request to store a data object in association with a smart data storage tier. Based at least in part on characteristics of the data object, the object-based data storage service identifies and stores the data object in a first location corresponding to a first data storage tier. The object-based data storage service monitors access to the data object to identify a second set of characteristics of the data object. This second set of characteristics is used to determine that the data object is to be transitioned to a second data storage tier. The object-based data storage service, based at least in part on this determination, stores the data object in a second location corresponding to the second data storage tier.

Abstract: Described herein are systems and methods of determining a distance between an object depicted in an image and an imaging device that captured that image. In particular, the disclosure discusses that an image may be separated into multiple derivative images, each of which is associated with a different wavelength of light. In some embodiments, an image may be separated into images associated with wavelengths of primary colors (e.g., red, green, and blue). Once separate images have been created, a sharpness value may be determined for each image. A distance between the object and the imaging device may then be calculated based on sharpness values associated with each of the separate images.

Abstract: Systems and methods are described for providing a predictive session-based search engine. A predictive session-based search engine may identify and pre-fetch data from various data sources that is likely to be accessed during a particular session. Data sources may include other search engines, databases, web servers, and other sources of information. A plug-in controller architecture, which may include templates, computer-executable instructions, application programming interface (API) calls, or other information that enables access to a particular data source, may be used to allow the predictive session-based search engine to obtain data from the data sources. The predictive session-based search engine may store and index the data it obtains, and may answer search queries during the session with data that is stored and indexed locally rather than retrieving data from the original sources.

Abstract: Technologies are provided for dynamically changing a size of a cache region of a storage device. A storage device controller writes data to the cache region of the storage device using a particular storage format. The storage device controller then migrates the cached data to a storage region of the device, where the data is written using a different storage format. A dynamic cache manager monitors input and output activity for the storage device and dynamically adjusts a size of the cache region to adapt to changes in the input and/or output activity. The dynamic cache manager can also adjust a size of the storage region. The storage device controller can automatically detect that the storage device has dynamic cache support and configure the storage device by creating the cache region and the storage region on the device.

Abstract: Embodiments herein describe a control system that determines a location of an item on a first conveyor belt which affects the transfer of the item from the first conveyor belt onto a second conveyor belt. The control system includes a distance sensor which determines a location of the item on the first conveyor (or a location of the item on a queue belt that provides the item to the first conveyor). Using the distance sensor, the control system can identify the offset of the item relative to the center of the first conveyor belt. The control system can then control the time at which the item transfers from the first conveyor belt to the second conveyor belt by, for example, speeding up or slow down the first conveyor belt to compensate for the offset or adjusting an induct time.
